RIVET-STIICKING MACHINE.

SPECIFICATION forming part Of Letters Patent No. 602,139, dated April12, 1898.

Application filed February 7, 1896. erial No. 578,362. (No model.)

One object of my invention is to avoid these difficulties.

Another object is to provide a small and inexpensive rivet-stickingmachine of great effectiveness and of great ease and convenience ofoperation which will be completely automatic, so that the completeoperation of sticking the rivet is the result of one complete movementof a treadle or other lever.

By using this machine the length of each joint of pipe is limited onlyby the width of sheet that can be had, and the operator at the same timehe punches the rivet-hole can stick a rivet in the hole he has punched,thus saving a great deal of time in the manufacture of pipe. 7

The principle of my invention is applicable both for round seaming andfor straight or long seaming.

In the machine as adapted for round seaming it is an object ofmyinvention to space the holes and guide the pipe so that the rivetswill be set at uniform distance and the seam will be true.that is, therivets will all be set in a plane at right angles to the pipe.

My invention comprises the rivet-sticking machine and the several partsand combinations hereinafter describedand claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a fragmental perspective view of a rivet-sticking machineembodying my invention asapplied for round seaming. Fig. 2 is afragmental perspective view illustrating the application of my inventionin a machine for straight seaming. is a crosssection cut through thestake, rivet-carrier, rivet-hole punch, and. rivet-hole-centering 1 pinof, the round seaming machine. The punch is not sectioned, and the pipeis shown in position with a rivetinserted through one rivet-hole andwith another rivet-hole ready punched, so that the pipe is ready to beturned to remove the rivet from beneath the holecentering pin and tobring the other rivet hole above the carrier to receive a rivet. Fig. 4is an enlarged fragmental detail on same line of section as Fig. 3, butshows the carrier in the position shown in Fig. 9. i Fig. 4 is anenlarged detail with carrier in the position shown in Fig. 3. Dottedlines show a rivet passing out. Fig. 5 is fragmentalelevation of therear end of the machine. Fig. 6 is a fragmental elevation of the frontend .Of the stake, with lower portions of the punch and thehole-centering pin. Fig. 7 is a perspective view of the machine. Fig. 8is a fragmental sectional view of the stake. The section is taken alongthe midline of the rivetrunway. The rivets are shown in position in therunway, but not in section. In this view and in Figs. 1 and 3 the partsare shown in the positionv occupied when the machine is at rest andafter the. pipe has. been turned to bring a rivet-hole into position toreceive a rivet. The position of parts shown in this view is that whichobtains both before the movement shown in solid lines in Fig. '9 andafter that shown in dotted lines in the same figure. The pipe is shownonly in Fig. 3. Fig. 9 is a fragmental section taken onthe same line asthat of Fig. 8, butshowing the parts in position for the rivet-movingmeans to move the line of rivets, so as to push the end rivet onto therivet-carrier. Dotted lines indicate the position of the parts when afarther movement of the slide has completed the operation of seatingsuch rivet upon the rivet-carrier. The position thus shown in dottedlines is the one which obtains when the foot-lever which operates themachine is fully depressed,while the position shown in full lines isthat which obtains at one moment of the downward movement of thefoot-lever. Fig. :10 is a fragmental plan of the round-seaming machine,looking downupon the rivet-runway. Fig. 11 is a plan of therivet-carrier and the clampingspring and block.

My newly-inventedrivet-sticking machine comprises the combination of thestake A, having a rivetrunway B therealong, means for'moving rivetsalong the runway, a rivet- IOO carrier 0, adapted and arranged forreceiving the rivet from the end of such runway and moving it toward theface of the stake, and means for operating such carrier. The means shownfor moving the rivets along the runway consist of a plunger orrivet-slide D, arranged at the rear end of the runway to reciprocateinto and out of the runway across the mouth of a chute E, through whichthe rivets are fed into the end of the runway. The rivet slide orplunger D is operated by suitable means which I will hereinafterdescribe.

The means for operating the rivet-carrier consist of a suitablerivet-carrier block 0, provided with a slideway c, and the bent slide 0arranged to play through the slideway to reciprocate the carrier blockand the carrier C, which is mounted thereon. Suitable means are providedfor operating the bent slide 0 and the means shown for this purposeconsist in a reciprocating slide F, with which the carrier sIide O isconnected by a suitable brace 0 This reciprocating slide F extends fromend to end of the stake and is operative] y connected at its rear endwith the rivet plunger or slide D and is also operatively connected withmeans arranged for reciprocating the slide F. Thestake A is providedwith the transverse bore a for the carrier-block and is provided on oneside with the slideway a, extending from the rear end to the front endof the stake across such crossbore a, and is also provided with theguideway a extending from the front endto and beyond the transverse boreto receive the bent slide 0 which is operatively connected with thecarrier by suitable meansviz., the carrier-block to reciprocate thecarrier. At the front end of the stake the slideway a is a round boreand at the cross-bore a and from there to the rear end of the stake suchslideway is a channel. The round-seaming machine is provided with arivet-hole punch G, arranged vertical, as With ordinary stakes, and thestake is provided with the ordinary bur-hole g, which, in the stake asshown, passes down through the transverse bore a, which serves as aguide for the rivet-carrier block 0, and such bore a is arranged at asuitable angle to such bur-hole, so that at the face of the stake thespace between the rivet-carrier and the bur-hole will be equal to thedistance desired between the rivets.

The rivet-carrier O is provided with a rivethead seat 2, which is flushwith the floor b of the rivet-runway B when the carrier-block is in itsretracted position, and is also provided with a rivet stop and guide 3,arranged to engage the stem of the rivet on the front side and upperside of the carrier-that is to say, upon the side of the carrieropposite the rivet-runway and upon the side of the carrier which istoward the rivet-hole punch.

II is a spring set stationary with relation to the stake at the underside of the path of the carrier and arranged to press upward toward thecarrier in the direction of the rivethole punch. The outer edge of thisspring is practically in the same plane with the rivetseat 2 of thecarrier when the carrier is fully thrown out to stick a rivet. Therivet-seat 2 of the carrier and the rivet stop and guide 3 011 the upperside of the carrier opposite the spring are so arranged with relation toeach other that when the rivet is seated upon the rivet-seat of thecarrier and the carrier is in its retracted position the guide willengage the stern of the rivet, while the lower edge of the rivet-headprojects beyond the lower side of the rivet-seat, so that when suchcarrier is in position and the rivet is pushed thereupon from therivet-runway the rivet-head will be engaged by the rivet-clamping spring11, as shown in Fig. 4E, and the rivet willbe clamped between the springand the upper stop and guide 3 on the carrier until the carrier has beenmoved sufficiently toward the face of the stake to insert the rivet intothe rivet-hole, and when this is done the rivet-seat is flush with thetop of the spring and the rivet is above and therefore released from thespring H. The rivet-clamping spring His fastened to a spring-holdingblock h, which is seated in the stake and secured'by a screw h.

The lower portion of the rivet-runway is wider than the head of therivet, and guideways Z) b are arranged one along each side of the runwayto engage the stems of the rivets and hold them in a right line anddirect them to and onto the rivet-carrier when the carrier isretracted-that is to say, in its lowest position.

I is a rivet-guide fastened to the stake and arranged above the carrierto allow the stem of the rivet to pass through such guide when thecarrier is moved downward. The guide opens downward away from the punchand is closed at its upper end, and the under side of the guide isprovided with a beveled face 1', against which the end of the rivet maystrike when the rivet is pushed outward by the carrier. and the upperpart of the guide 3 of the carrier are arranged in such relation thatwhen the rivet clamped by the spring is pushed upward by the carrier itsend will first engage the beveled face i of the guide and will therebybe moved downward slightly. The upper end of the gnidewayi of the guideI is closed and is-in exact position to register with the upper edge ofthe centering-pin and the upper edge of the rivet-hole which has beenpunched at the moment the pipe is in position for the succeedingrivet-hole to be punched, so that when'the pipe is in position for thesucceeding hole to be punched the operation of the carrier will serve toforce the rivet into the hole which has been punched.

J is a rivet support arranged along and beneath the rivet-guide andextending downward, as shown in Fig. 3, to carry the rivet below thepoint where it would drop out of its hole after being insertedthereinto-that This beveled face, the spring,

is to say, to the position in which the stem of the rivet will behorizontal or inverted.

K indicates the rivet-hole-centering pin adapted and arranged to bemovedtoward and from the stake in the extended path of therivet-carrier. It reciprocates axially. to enter the rivet-hole and tobe withdrawn therefrom. indicates the spring which forces this pintoward the stake, and when the pipe is placed upon the stake the pin Kis springpressed against the pipe, so that when a rivethole has beenpunched by the punch G and the pipe turned the pipeP will be engaged bythe pin K until the upper edge of the rivethole registers with the upperend of the rivetguideway 2' and at that instant the springpressedrivet-hole-centering pin K will be forced into such rivet-hole, thusstopping therotation of the pipe and holding the pipe in position foranother rivet-hole to be punched, and also in position for the insertionof the rivet from beneath. Then when the machine is operated to forcethe rivet up into the rivethole in the pipe the end of the rivet-stemwill engage the centering-pin and carry it up out of the rivet-hole andthus leave the pipe free to be again turned after the succeeding rivet-'hole has been punched. When the pipe is thus turned, it slides therivet off from the carrier and out from under the centering-pin (whichimmediately engages the surface 'of the pipe ready to enter the nextrivet-hole when it comes under it) and along the guide and over therivet-spring and the rivet-support until the V succeeding rivet-holecomes beneath the centering-pin. Then the pin enters such'hole and theoperation just described is repeated.

L indicates a catch for holding the centering-pin away from the stakewhen it is desired to remove the pipe from the stake or place thereupona joint of pipe.

M is a rocking shaft provided with thefootlever m at the front end ofthe stake and extending back to the rear of the stake, where it isconnected by suitable means 4, 5, 6, 7, and 8 with the reciprocatingslide F. A spring Nis arranged to hold the rocking shaft in position tohold the slide F fully retracted to the left, and thus to hold thecarrier 0 in its raised position, such as shown in Figs. 3, 4.,

and 8. The downward movement of the footlever against the action of thisspring throws the slide F to the right from the position shown in Fig. 8andinto the position indicated in solid lines in Fig. 9, thus to retractthe carrier so as to bring its seat flush with the floor of the runway,as shown in Figs. 4 and 9, and a further and final downward movement ofi the foot-lever operates the slide or plunger D sufficiently to forcethe rivets forward and seat the front rivet onto the carrier. i

In the operation of the machine the chute E will set one rivet at a timein position to enter the runway B, and at each forwardmovement of theplunger D this rivet is carried forward, this carrying the line ofrivets 0 forward and seating the front or end rivet, as above stated,upon the carrier. The footlever is arranged so that it does not completeits downward movement until the plunger D a hammer and punches arivet-hole in the pipes. Then he turns the pipes to the left untilstopped by the rivet-hole-centering pin K,

which enters the rivet-hole as soon as it comes beneath it. The workmanthen strikes-the rivet-hole punch again and at the same movementoperates the foot-lever m with his foot,

Then he relieves the foot-lever and'allows the spring N to bring themachine to its first or normal position, and at the same time he turnsthe pipe and from thence the operation is the same as that justdescribed until the circle of rivets is complete. Then the pipe iswithdrawn sufficiently to allow the workman to hammer the rivets andfinish the joint. In the straight-seam machine the rivet-hole punch Gand the rivet-hole-centering pin K are arranged in line parallel withthe stake,

and in sticking rivets for straight seaming the operation is the same asthat above described, except that instead of turning the pipe theworkman pushes the pipe onto the thus sticking a rivet in the firstrivet-hole.

stake the space between two rivet-holes each time a hole is punched anda rivet stuck.

J indicates a rivet rest and shield above the rivet-runway B of thestraight-seam machine.

In the straight-seam machine the rivetguide 1 extends along instead ofacross the stake,'and the rivet-support J is dispensed with, its officebeing performed by the rivetrestJC' In both the round and the straight,seammachines the punch and the rivet-hole-centering pin are arranged inthe plane in which the seam is to be made. In the round seam this planeis at right angles, to the stake and in the straight seam it'is parallelwith the stake.
